One issue that the owner has brought up is that sometimes he has trouble filling the 4th unit, but said that is primarily because his daughter, who manages it for him, isn't always diligent about advertising it. 

The contract becomes an issue when the parties start to disagree.

I can't speak for others, but the only time I see these types of issues being brought up are from people that have a financial interest in doing so.

Assign each house a "Class" and tag each transaction with the appropriate Class. 

I wonder if I have to wait til the 11th to issue the detainer warrant?

Could someone point me in the right direction or give me a link to where these government rules are posted?    

The big issue comes in with the repayment clause on the loan if you lost the job, as it would put you in a cash call type position.Ideally you would use the money on a down payment on a BRRRR scenario- and then when you refinance you repay the loan balance.  

Great of you to get linked into BP here and join the community, it's another great place to contribute! 

Or are there some issues I may be looking over?

I would be more concerned about 'issues' than a particular score.
